Definitions

  • the invention relates to a clip for a flexible tube in the interior of which the pressure prevailing is different from that in its environment.
  • Flexible tube clips of this kind are therefore suitable for both sub-and superatmospheric pressure systems.
  • a preferred field of use of a flexible tube clip of this kind is medical technology, in which a clip of this kind can be used as a connection means for a vacuum suction flask for drawing off wound fluids in the drainage of wounds.
  • a suction flask of this kind is connected by means of a flexible tube to a perforated wound drainage tube, which in turn is introduced into a hermetically sealed wound cavity.
  • the negative pressure prevailing in the suction flask thus also acts in the wound cavity, so that wound secretions forming there can be sucked off into the flask.
  • sliding clips are known (DE-A-37 24 483) for closing a flexible tube, such as for example the tube disposed between the vacuum suction flask and the wound drainage tube.
  • These sliding clips have two fork-like prongs which are fastened to one another, widening out in a V-shape. By sliding these prongs lengthwise relative to the tube, the cross-section of the tube can be compressed and the tube thus closed.
  • Sliding clips of this kind permit practically no regulation, that is to say partial closure of the tube cross-section.
  • a flexible tube clip of the type defined, with the aid of which the cross-section of a tube can be closed to a greater or lesser extent for regulation purposes, is known from DE-B-23 56 480.
  • the valve of a container disclosed there is provided in its cover region with a lever which rests on both a rubber balloon and a flexible tube.
  • this lever has a double mounting so that it can turn in both the clockwise direction and the counter-clockwise direction.
  • the interior of the rubber balloon is connected to a pipe projecting into the interior of the container.
  • the flexible tube, on which the lever likewise rests, constitutes an additional connection of the interior of the container to the environment of the container.
  • the lever On the contraction of the rubber balloon, that is to say on a reduction of the volume of its interior space, the lever turns, for example, in the counter-clockwise direction.
  • the lever When the rubber balloon is inflated, that is to say on the enlargement of its interior space, the lever turns in the clockwise direction, that is to say in the opposite direction.
  • the lever reduces the load on the flexible tube, so that the cross-section of the latter is enlarged in both cases. Since the interior of the rubber balloon is in communication with the interior space of the container via the pipe, the pressure in the rubber balloon will become equal to that prevailing in the interior of the container. If the internal pressure of the container falls below a predetermined value, the rubber balloon will contract and free the cross-section of the flexible tube.
  • the pressure inside the container thus rises again to the preset value. If, on the other hand, the internal pressure of the container exceeds the predetermined value, the rubber balloon expands and the cross-section of the flexible tube will likewise open. This has the consequence that the positive pressure in the balloon is reduced and drops back to the preset value.
  • This flexible tube clip thus serves to regulate the internal pressure of the container to a determined value dependent on the outside pressure. When the internal pressure in the container falls below a determined value, this lower pressure which is adjusted is immediately raised again by the opening of the cross-section of the flexible tube. The cross-section of the flexible tube thus does not act as a throttle point. It is thus not possible to ensure that outside the more or less sharply constricted cross-section of the flexible tube a constant negative pressure largely independent of the negative pressure prevailing in the container can be maintained.
  • the problem underlying the invention is that of providing a flexible tube clip of the kind indicated in the preamble, which constitutes a simple possible way of reducing the cross-section of a flexible tube in order thereby to form a throttle restriction at that point in the cross-section of the tube.
  • the flexible tube clip according to the invention for a flexible tube which is connectable to a container and in whose interior the pressure prevailing is different from that in its environment, according to the preamble of Patent Claim 1, is accordingly characterized in that the connection between the interior space of the subsidiary chamber and the flexible tube is a subsidiary tube or an opening provided only outside the container, the subsidiary tube or the opening is connected, in relation to the clamp point, on the side of the flexible tube remote from the container which is to be connected, the arms are disposed on the wall of the subsidiary chamber in such a manner that through variation of the volume of the subsidiary chamber the arms are movable relative to one another and the flexible tube can thereby be compressed to different extents, while the two arms of the body forming the subsidiary chamber move towards one another when the negative pressure in the flexible tube increases, and the two arms of the body forming the subsidiary chamber move away from one another only when the negative pressure in the flexible tube is reduced.
  • a flexible tube clip of this kind installed in a tube connection between, for example, a vacuum suction flask and a wound drainage tube, can thus act independently as a throttle valve because the pressure prevailing in the tube also acts through the subsidiary tube in the interior space of the subsidiary chamber and has the effect of correspondingly adjusting the interior space in relation to the prevailing outside pressure.
  • this negative pressure prevails in the tube, this negative pressure thus also acts in the subsidiary chamber, so that the latter can contract and thus, the at least one arm connected to it can make a relative movement toward the other arm. This in turn has the consequence that the arms will compress the cross-section of the tube to a determined extent.
  • the tube clip will compress the tube to such an extent that equilibrium is achieved between the negative pressure acting through the cross-section of the tube, and the negative pressure in the subsidiary chamber.
  • the subsidiary chamber is formed by a bellows-like body which is disposed between the two arms in such a manner that through the expansion or contraction of said body the arms are movable relative to one another and thus, the tube is compressed to different extents.
  • the two arms it is expedient for the two arms to be swivellably fastened to a sleeve member; the sleeve member can in this case be so constructed that it can be pulled over the respective tube which is to be pinched by the clip.
  • the bellows-like body is fastened by its two end regions to the two arms. The throttle action of a tube clip of this kind depends on the materials and the constructional arrangement relative to one another of the individual components used.
  • an elastic body acting as damping means can be additionally disposed between the two arms.
  • the throttle action can be strengthened or weakened.
  • this effect can also be achieved through the fact that the bellows-like body can be fastened at various points along the arms.
  • the arms are disposed on the wall of the subsidiary chamber in such a manner that through variation of the volume of the subsidiary chamber the arms are movable relative to one another and the flexible tube can thereby be compressed to different extents, while the two arms of the body forming the subsidiary chamber move towards one another when the negative pressure in the flexible tube increases, and the two arms of the body forming the subsidiary chamber move away from one another only when the negative pressure in the flexible tube is reduced.
  • a flexible tube clip of this kind installed in a tube connection between, for example, a vacuum suction flask and a wound drainage tube, can thus act independently as a throttle valve because the pressure prevailing in the tube also acts through the subsidiary tube in the interior space of the subsidiary chamber and has the effect of correspondingly adjusting said interior space in relation to the prevailing outside pressure.
  • this negative pressure prevails in the tube, this negative pressure thus also acts in the subsidiary chamber, so that the latter can contract and thus the at least one arm connected to it can make a relative movement towards the other arm. This in turn has the consequence that the arms will compress the cross-section of the tube to a determined extent.
  • the tube clip will compress the tube to such an extent that equilibrium is achieved between the negative pressure acting through the cross-section of the tube and the negative pressure in the subsidiary chamber.
  • the subsidiary chamber is formed by a bellows-like body which is disposed between the two arms.
  • the two arms between which the body is disposed can in this case be so constructed that it can be pulled over the respective tube which is to be pinched by the clip.
  • the bellows-like body is fastened by its two end regions to the two arms. The throttle action of a tube clip of this kind depends on the materials and the constructional arrangement relative to one another of the individual components used.
  • an elastic body acting as damping means can be additionally disposed between the two arms.
  • the throttle action can be strengthened or weakened.
  • this effect can also be achieved through the fact that the bellows-like body can be fastened at various points along the arms.
  • the bellows-like body it is also possible to provide a piston and cylinder arrangement, in such a manner that the interior space of the subsidiary chamber is in this case formed by the interior space delimited by the cylinder, the piston and the wall of the tube.
  • at least one of the arms is fastened to the piston in such a manner that on the displacement of the piston in the cylinder said arm is moved transversely to the longitudinal axis of the tube.
  • the other arm, which bears against the tube can in this case be stationary.
  • the second arm may also be formed by some other construction surrounding the tube, such as for example a wall part.
  • the piston is movable in the direction of the tube against the force of an elastically deformable body.
  • This elastically deformable body may be an elastically resilient spring.
  • the tube it is, however, also possible for the tube to be made elastically resilient, at least in its region which is compressible by the arms. If the tube is completely compressed, and thus its wall undergoes maximum deformation in this compressible region, the restoring fore existing in the tube wall will be directed against the piston force pressing against it, so that on a reduction of the negative pressure in the subsidiary chamber, the restoring force of the tube will push the piston away from the tube wall and therefore back.
  • FIG. 1 is a view in perspective of a vacuum flask with an attached connecting flexible tube to which a first embodiment of the tube clip according to the invention is fastened,
  • FIG. 2 is a plan view of the tube clip shown in FIG. 1, mounted on the connecting tube,
  • FIG. 3 is a side view of a second embodiment of a tube clip according to the invention, mounted on a vacuum flask, in its throttle position,
  • FIG. 4 is a side view of the tube clip shown in FIG. 3, partly in section, and
  • FIG. 5 is a longitudinal section through the tube clip according to the invention shown in FIG. 3, with the suction flask in the closed state.
  • a bellows 12 of plastics material On a first opening of a vacuum suction flask 10 is disposed a bellows 12 of plastics material, which is surrounded by a transparent, approximately cylindrical protective cup 14 (FIGS. 1 and 2).
  • the bellows 12 and the protective cup 14 serve as a pressure indicator 16 for the negative pressure prevailing in the interior of the suction flask 10.
  • a bellows 12 at maximum expansion indicates a minimum negative pressure in the suction flask 10, and an extremely highly contracted bellows 12 indicates a maximum negative pressure therein.
  • a tube 18 is connected to a second opening of the suction flask 10. This tube 18 is connected via a tube fork 20 to a tube 22 which can be connected to a drainage tube (not shown).
  • connection piece 24 is engaged over the tube 18. At its end directed away from the suction flask 10 this connection piece 24 is provided with a collar piece 26. Two arms 28, 30 are swivellably fastened by their ends, with the aid of respective joints 32 and 34, to said collar piece 26.
  • one end of a tube 48 is connected with the aid of a connection piece 46.
  • the other end of said tube 48 is connected to the still free end of the tube fork 20.
  • the tube 18 and the tube 22 are fastened to the other two ends of said tube fork 20.
  • the tube clip 50 mounted on the tube 18 operates in the following manner:
  • This reduced negative pressure thus also acts in the tube 22 and consequently also in the wound drainage tube which, for example, is connected to the latter.
  • a reduced negative pressure therefore acts in a, for example, human wound from which wound secretions are to be sucked off into the vacuum suction flask 10.
  • a sliding clip 60 shown in dot-dash lines, is pushed on the tube 18 in such a manner that the latter is completely closed at that point.
  • the bellows 38 is thus connected to the atmosphere existing outside the bellows 38, so that it is at maximum expansion.
  • the bellows 38 which for reasons of economy is made of plastics material, is therefore in the relaxed state. Its elastic deformability is thus not impaired; this could not otherwise be ensured if it were kept compressed for a long time because of the risk of fatigue of the plastics material of which it is made.
  • the sliding clip 60 is removed from the tube 18.
  • the bellows 38 will thus abruptly contract and compress the tube 18 to a predetermined extent, as illustrated by way of example in FIG. 2.
  • the tube clip 62 which is illustrated in FIG. 3 comprises a casing 64 provided with a bottom connection piece 66 and a top connection piece 68.
  • the bottom connection piece 66 is fitted gastightly on the neck 70 of the vacuum flask 10.
  • a transition tubing piece 72 is fitted, likewise gastightly, between the connection piece 66 and the neck 70. This tubing piece 72 passes through the interior space 74 of the casing 64 and projects out of the casing 64 in the region of the top connection piece 68.
  • a flexible tube 18.2 is gastightly connected in the region of the top connection piece 68. The interior of the tube 18.2 is thus connected to the interior of the vacuum flask 10.
  • the casing 64 On the two sides of the transition tubing piece 72 the casing 64 has a left-hand flange 76 and an oppositely disposed right-hand flange 78.
  • a wall 80 adjoins the left-hand flange 76. This wall has a central cantilever projection in the form of a left-hand arm 82.
  • the wall 80 and therefore also the casing 64 are in contact with the transition tubing piece 72 only in the region of said left-hand arm 82, that is on the left in the drawing.
  • a cap-like cover 84 On the side of the casing 64 opposite the wall 80 the flange 78 disposed there is covered by a cap-like cover 84. An opening 86 is formed in this cover 84, so that the atmospheric pressure prevailing outside the cover 84 also acts inside the latter.
  • a piston 88 is guided in the flange 78 for longitudinal sliding, towards the left and the right in the example illustrated.
  • the piston 88 bears gastightly against the inside of the flange 78.
  • this piston 88 is made of rubber.
  • Said piston 88 has a cantilever projection in the form of a right-hand arm 90, which in relation to the transition tubing piece 72 is disposed exactly opposite the left-hand arm 82.
  • the transition tubing piece 72 is compressed to an extremely great extent in the region between the left-hand arm 82 and the right-hand arm 90. This condition is illustrated in FIG. 5.
  • An opening 92 is provided in the wall of the transition tubing piece 72 in the region of the casing 64.
  • the pressure in the interior space of the transition tubing piece 72 can thus come into equilibrium with the pressure prevailing in the casing 64 between the wall 80 and the piston 88.
  • the cover 84 and the flange 78 are provided with an interlocking device 94, for example of the bayonet type, so that the cover 84 can be fastened in its position shown in FIG. 5. IN this position of the cover 84 the latter, by means of all parts 96 formed on it, presses the piston 88 extremely far to the left, so that the transition tubing piece 72 is completely compressed. The pressure prevailing in the vacuum flask is thus retained in the latter.
  • the position of the tube clip 62 shown in FIG. 5 is that before the suction flask 10 is used. In this position, the vacuum flask 10, with the tube clip 62 attached to it, is taken to a patient.
  • the cover 84 is unlocked, that is to say the bayonet-type locking device 94 is unlocked.
  • the cover 84 will then occupy approximately the position shown in FIG. 3, which means that the passage through the transition tubing piece 72 is opened to a greater or lesser extent.
  • the negative pressure prevailing in the vacuum flask 10 will then be propagated through the tube 18.2 into the region of the patient's wound.
  • a throttle point is thus likewise formed.
  • This throttle point is influenced by the position of the piston 88.
  • the outside pressure prevailing outside the casing 94 for example atmospheric pressure, which can also establish itself in the interior space 74 of the cover 84 by way of the opening 96, acts on said piston 88 from the direction of the cover 84.
  • the suction pressure which results from the negative pressure in the vacuum flask, and is normally lower than the outside atmospheric pressure, will act.
  • this pressure can also establish itself on the side of the piston 88 which is on the left-hand side in the drawing, in the interior space 74.
  • the piston 88 is moved to the right because of the elastic construction of the transition tubing piece 72, that is to say because of its restoring force.
  • a more or less sharply defined throttle point will thus be formed between the arms 82 and 90 inside the casing 64.
  • the tube clip 62 thus also provides a very simple possible way of self-regulating formation of a throttle point in a flexible tube.
